Here's what I see in the traces you sent me:

-u [/tmp/sshpass][14066]{3783827} fork() ................... (returning
as child ...) ......... = 14064 {3783821}

The child process is 14066.

-u [/tmp/sshpass][14066]{3783827} setpgrp3(2)
................................................. [entry]
-u [/tmp/sshpass][14066]{3783827} setpgrp3(2)
................................................. = 14066


Start a new session, disconnecting from the previous TTY

-u [/tmp/sshpass][14066]{3783827} open(0x400132d0, O_RDWR, 01210)
............................. [entry]
-u [/tmp/sshpass][14066]{3783827} open("/dev/pts/5", O_RDWR, 01210)
........................... = 6

Open /dev/pts/5 with the flags O_RDWR. According to Posix, at this point
pts/5 is supposed to become the controlling terminal for the new
process. This, obviously, does not happen.

At this point I need to return the responsibility to this problem to
you. As far as I can tell, the process is not behaving the way it
should. I have no tools for investigating this any further than that.

If you can find out why opening a TTY device does not turn it into the
controlling TTY of the process, please do let me know, and I can work
that into sshpass.
